Quality Control

Our 1-[(2S,3S)-3,4-Dihydro-3,5,7-trihydroxy-2H-1-benzopyran-2-yl]-8-[(2R,3S)-3,4-dihydro-3,5,7-trihydroxy-2H-1-benzopyran-2-yl]-3,4,6-trihydroxy-5H-benzocyclohepten-5-one is manufactured under strict quality systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure compliance with stringent specifications. Certificates of Analysis (COA) detailing all test results are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere such as nitrogen or argon for long-term stability. Keep the container tightly sealed to minimize exposure to moisture and air.
